The adaptation path of environmental governance in the Yellow River Basin for regional ecological improvement

Protecting the ecological environment of the Yellow River Basin (YRB) is the key to promoting high-quality development of the whole YRB. Based on the information on environmental governance and the ecological environment in the YRB from 2016 to 2020, we constructed the regional eco-environment index (ECI) of the YRB, measured the government’s environmental governance capacity, and used the entropy weight method and relevant spatial statistical tools to reveal the spatial distribution characteristics of the ECI in the YRB. In addition, we used the method of configuration qualitative comparative analysis to explore the adaptation path of environmental governance for improving the ECI. The study showed that the regional ECI of the YRB was obviously heterogeneous, showing a spatial pattern of “good in the upstream, middle in the downstream, and depressed in the midstream.” There are three appropriate paths for environmental governance to improve the ecological environment: the government efficiency-oriented, rule of law-oriented, and pressure-oriented paths, among which the government efficiency-oriented path is the most common path. The findings propose the governance path of the ecological environment in the YRB from the perspective of configuration, reveal the configuration relationship among the factors affecting the government’s environmental governance, broaden ideas for solving ecological environment improvement problems in the YRB, and enrich the research methods of the government’s environmental governance.
